 +There are different revisions of this board and the sample here 
 +is the MB997C. One difference between this and the original board
 +revision MB997B is that they changed the MEMS sensor from the
 +LIS302DL to the LIS3DSH. The LIS3DSH is now obsolete and has been
 +replaced by the LIS3DH.

 +VCP on the board is supported, however, the pins were left unconnected and
 +ST propose you use jumper leads to fix this oversight.
